Specification of Letters Patent. Patented'oct, 12, 192()f Applicationfiled November 20, 1919. Serial No. 339,486.

i To all whom il?? may concern.'

The primary object of the invention is tol provide a simple, economical,accurately adjustable element, so arranged and constructed, as toprevent back pressure of the gas and to discharge an unbroken column ofgas into the burner tube, whereby perfect combustion is maintained undervarying low pressure conditions of the fuel gas.

The invention therefore embodies as its essential features a fluidsupply nipple having an orificed tip provided withinternal conicalwalls, which converge toward the discharge orifice to form a choke bore.T he tip thus formed is equipped with a plug 1ncased therein having aconically beveled end corresponding in pitch to the conical bore of thetip, whereby the tapered surfaces of said tip and plug together form aparallel conically disposed smooth fluid discharge thereat leading tothe orice, which throat isadjustable by a telescoping actionwlthrelation to the tip and plug to contract and expand the throat inorder to adjust the fuel supply.

The invention also contemplates the adjustment of the plug member ortip, whereby the conical throat is contracted or .expanded to vary thequantity of gas supplled to the burner under all conditions both as tovolume and richness.

The invention also contemplates the embodiment of a simple andeconomical mixing chamber in connection with the burner tube togetherwith means for varying the air inlet ports, whereby the supply of air tothe burner is controlled and admitted uniformly about the solid columnof gas which is vdischarged through the mixing chamber and.

into the burner tube.

WV ith the above and other objects 1n lview which will hereinafterappear as the description continues, the invention consists of the novelfeatures of construction, combination and formation of parts as will behereinafter more fully described and particularly pointed out'in theappended clalms.

, In the accompanying drawings has been i shown a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details herein exhibited,but

the right is hereby reserved to any changes, alterations ormodifications to whichl re-v course may be had that come within thescope of the claims without departing from the spirit of the inventionor sacrificing the efficiency of the same.

In the accompanying drawings: f Figure 1 is a bottom plane elevationwith the furnace wall in cross'section, illustrating the entire mixingapparatus and' its relation to the furnace. Y Fig. 2 is a plan view ofthe burner, ignition plate and the mixing tube;

Fig. 3 is a longitudinal section of the apparatus,` with the operativeelements in" elevation;

Fig. 4 isa longitudinal sectional view of` the mixing tube; and, 4. p. Y

Fig. 5 is a section on line 5 5 of Fig. 2.

Referring by characters to the drawings, 10 represents the pipe lineleading from the reservoir 11 adapted for the storage of oil comprisingthe fuel utilized. This pipe 10 Y is connected by the elbow 12 to asimilar pipe 13 having its threaded end lifscrewed into an openingformed in a sleeve 15 of semi-tubular construction. A pipe 16 leads froma tank 17 and is connected to the convoluted coil section 18 by a pipesection 19 and elbows 20.

'Pipes 10 and 19 carry globe valves 2O and 21, which are operable toregulate the feed of the oil and air respectively. A pipe 22 isconnected to the pipe 23 of the coil section 18, which latter ispositioned below the burner element to be later more fully described. v.v

A sleeve 1 5 is formed with an'interiorly disposed annular channel 24:and a centrally located tube 25 extends outwardly from the solid portion26 of said sleeve to a point beyond the open end thereof.v The oppositeend of sleeve 15 'is formed withy a restricted threaded `shank 27 onwhich is screwed a cap 28. As will bel readily seen, the annular channel24 entirely surrounds the greater part of tuber andthe pipe 22 leadingfrom the compressed air reservoir 17 opens into said channel 24.

The solid part of 26 of sleeve 15, is providedV with an Aopening 29communicating with the hollow interior 'of tube 25 and the oil pipe 13has its threaded end seated` into this opening 29, so that the fuelsupply enters into the tube. j

The discharge end of tube 15 is formed with a Y concaved basin 30, thecenter of which basin merges into a central discharge orifice' 31 whichforms a truncated valve seat 32 in the lwall 33. This wall 33 forms achamber 34 within the hollow extension 35 of the said sleeve. Anipple36is adjustably mounted upon the outer end of sleeve 15 and is formed witha restricted and out'- wardly projecting extension 37.V The outer vendof tube 15 extends into the extension 37 i of nipple 36 and the saidnipple is connected tothe convoluted burner tube 38.

A needle stem 39 extends through Vopenings 40 and 41, in the cap 28 andshank 27 and into the hollow interior of the tube 25 of said sleeve 15.

The inner end of theneedle stem 39 carries a restricted shank portion 42to which is secured the valve head 43 which "cooperates with the seat-32 in extension V34 of the sleeve. V'Ihe needle Vstem isthreaded at 44at which point it engages an interior portion of the sleeveV 15.Likewise the outerv wardly andoutwardly with respect to said sleeve andtube 15, and to seat and unseat the valve Vhead 43 from seat 32. In thismanner the flow of fuel oil passing through VtubeV 15 and into theextension through the restricted opening 33 is-regulated. f

The mixing of the air with Vthe fuel oil is eifected in the followingmanner:

' A hollow cylindrical casing member 47 is connected to the restrictedportion 37 of nipple 36 and is formed with a closed outer end 48 whichlatter is formed with angularly disposed openings 49 and: a centralopening. The restricted portion of nipple 36extends`through,the centralopening of the casing member 47. j v

` The casing member 47, comprises the mixf ing chamber of the device andthe relatively thin stream of fuel oil passes through the nipple 36and'mixes with the heated air undercompression, just beyond therestricted portionV or extension 35 of the tube 25 and` for thoroughlybreaking up the molecules j of air and fuel to provide a rich gaseousmixture, I pass the fuel vapors through a The air under compression ispassedVV through the pipe coils v18 located directly under the burner 38and .is consequently heated thereby, Vs'o that when it is delivered for?admixture with the fuel vapor its caloric intensity and value is greatlyaugmented and consequently the maximum degree of' commlngling of the airand gas molecules is effected.

An ignition plate 51 is connected to the casing member47 just below theburner 38 and justprior to igniting the gaseous mixture a quantity ofgasolene' or free oil is placed upon the plate 51 and ignited, whichaction heats the air in coils 18.

For providing for an auxiliary air admission to the mixing chamber, 'Imount a mov able cap 52 ony one end of the casing memberl 47 and said ca52 regulates the air openings 49.V Shou d -a greater supply of air berequiredl inthe mixing chamber, thisA cap 52 maybe adjusted to bring theopenings 53 therein, in registration with the openings 49 ofsaid casing,to cut off the auxiliary" air supply, itwould only bevnecessary toadjust the cap 52 i to cover the casing openings 49.V f

y While in this speclcation the compressed air is employed it isunderstood'that if d`e` suitable gas may be' sired steam or other used.Y

Having' thus fully described my: invention, what I claim as new anddesire to secure by Letters Patent is 1. A gas generator, comprisinga-burner, a mixing chamber connected to said burner, a nipple adjustablymounted on said cham ber, a hot air supply pipe connected to saidnipple, a gasolene or oil supply pipe formed interiorly of said gasolenepipe, a shaft extending long'itudinally within said gasolene pipe andhaving threaded engagement with I the rear portion of said gasolene andair pipe casing, a vtruncated conical valve head secured to said shaftfor regulating the flow of gasolene or oil to the mixingv chamber, saidnipple being adapted for'adjustment to regulate the hot air supplyl tothe mixing chamber, an auxiliary yairsupply member mounted on saidlmixing* chamber, a double truncated screen member disposed within saidmixing chamber for breaking up the molecules ofV airv and gasoleneintroduced therein, and means whereby the air is heated prior to sameentering the mixing chamber.

2. A gas generator comprising a burner, a mixing chamber connected tosaid burner, a nipple adjustably mounted on said chamber, a gasolenesupply pipe, a hot air supply pipe connected to said nipple, a fuelsupply pipe formed interiorly of said gasolcne supply pipe, a shaftextending longitudinally within said gasolene pipe and having threadedengagement with the rear portion of the said gasolene and air pipecasing, a truncated conical valve head secured to said shaft forregulating the flow of gasolene or oil to the mixing chamber, saidnipple being adapted for adjustment to regulate the hot air supply tothe mixing chamber, and an auxiliary air supply member mounted on saidmixing chamber and means within the mixing chamber for breaking up themolecules of air and gasolene introduced therein, and means whereby theair is heated prior to its entrance to the mixin chamber.
